rebuild parts needed

Well my 85 gpz 600r is up for a rebuild and not wanting to part with a heap of cash, i thought id check with you guys to see if anyone knows of somewhere i can get things a bit cheaper then my local kawi dealer.

i looked on the net but had little sucess.

i havnt pulled it apart yet but im looking at.

pistin & rings / gaskets / bearings (all) / and some gear box bits exactly what i dont know at this stage.

thanks
